PHYM003 Condensed Matter II 2017-18
Dr S. Russo
Delivery Weeks: T2:01-11
Level: 7 (NQF)
Credits: 15 NICATS / 7.5 ECTS
Enrolment: 47 students (approx)


The module will apply much of the core physics covered in PHY2021, PHY2024, and PHY3051 to novel systems and engage with fundamental electric, magnetic and optical phenomena in metals and dielectrics. The module illustrates and draws on research undertaken in the Department: studies of the metal-to-insulator transition, oscillatory effects in strong magnetic fields, optical and magnetic phenomena.

Module Aims

The module aims to develop understanding of effects that played a key role in the development of contemporary solid state physics and to provide a general description of its current trends. The different topics covered will be linked by the idea that electrons in solids can be treated as quasi-particles interacting with other quasi-particles: electrons, phonons, photons. In addition to electrons, other excitations in solids are considered, e.g. Cooper pairs, plasmons and polaritons.
